[Why & How]
Dmesg errors are found on dcn3.1 during reset test, but it's not
a really failure. So reduce it to a debug print.

(cherry picked from commit 1d925758ba1a5d2716a847903e2fd04efcbd9862)
---
Add extra define guard for the backport to ensure debug messages only
come up when compiled with DCN on 5.16.

Backport to 5.16.y only, different backport for older kernel.
